means are provided, in combination with a set ot'spixral `heating coils,#for additionally V `heating tllezheaterfl water delivered by sach sotor sets or spiral heating coils,the `whole beinCr arranged to reducelosses otheat to a .b i, C i

Further features and objects oi? the in` ventionare more :fully setforth in the `tollowing description and the accompanying drawing,showing in vertical elevation partly in vertical section, one embodimentoi the invention.

Referring to the drawings, 1 represents the burner of any approveditype,and 2 the casing, usually provided with the outlet 3, for the dischargeoi: the products oi2 combustion, which outlet maybe varied orniodifiedaccording to circumstances, as will be understood.

4 represents a set of heating coils, suitably connected at one end 5with the cold water supply pipe 6. The discharge end ot such a set ofspiral coils 4 is indicated at 7.

'llo such discharge 7 is connected the `additive heater 8 comprising themain chamber 9 extending from aregion in adjacent heatfio ing relationto the burner 1 upwardly, and preferably through the outlet 3 of thecasing 2, said additive heater 8 being connected at its upper end te theriser 1 ()l` and thus with theboiler or reservoir 11. rlhe dischargepipe of the reservoir 11 is indicated at 12.

Preferably, also, the connection of the main chamber 9 with thedischarge terminal 'i' ofthe heating coils 4, is effected by means ofthe pipe 131 arrangedas a chamberdisposed inwardly or withintheadditiveheater chamber 9 and discharging at its lower end p 14 into thelowermost portion 15, as indi cated` by the arrows 16.

Such preferred form of the invention proi vides the reduced region 17,of more or less annular formation, immediately adjacent the outer `wallof the additiveheating chamber the inner or other liuid` is `subjecteddirectly to the heat of the flame oit the burner 1, and. providesfurther for the passage of the water or other fluid, previously heatedin the coils water or other liquid in theadditive hea-ting chamber 9 ofhigher temperature.

To "attain more fully the aforesaid results` the chambers 9,13, eitheror both, are corrugated, as by threading, or otherwise provided withprojecting, relatively thin por- `tions 18, to increase the transferenceolheat.

VFor simplicity of manufacture and. assein bly, the `outer chamber 9 andinner chamber 18 may be formed oi pipe of lproper diam eters, the outerpipe being' closed at its lower end by the cap 19 and connected atitsupper end to the riser by means of the reducer 20. The connection ofthe discharge end 7 ot the coils 4 may be simply attained by means ofthe pipe section 21, threaded at one end into the openings 22, 23,respectively of pipe 13 and outer pipe 9, and connected with by means ofthe elbow 24, nipple and the union 26.

Preferably, as shown, the connection of the .section 21 with the innerchamber or pipe .i3 is effected by means of the reducer 27, connected atits larger opening 28 with the chamber' or pipe 13 and its smaller opening 29 communicating interiorly of the outer reducer 20, whereby uponlighting` the burner l, .heated water is supplied to the boiler orreservoir 11 initially jointly from the chamber 9 and the coils 14. Suchar-` rangement is advantageous in that a larger quantity of heated wateris supplied promptly after first lighting the burner.

Under conditions of continued heating by the burner, by reason of theadditive heater 9 being disposed in the region of higher temperature ascompared with the coils 4, the ellective temperature of the water in theadditive heater chamber 9 becomes y more land more -increased andaccordingly upon 9, whereby a relatively thin layer of water i `4,.through the chamber' 13 surrounded by i lll) ` the spirit of theinvention, as delinea appended claims.

warm water in large quantity upon initial lightingl of the burnerandvinaterialy increasing the temperature or additively heating theWater upon continued lighting of the burner, is particularly effectivewhen the Water is caused to flow through the discharge 12, i. e., byturning' on the faucet.

The invention applicable in use as en attachment of the additive heaterto au ordinary hot water heater provided with such set or vsets ofspiral coils, such attachment beingreadilyv effected withoutdisturbii'nr the water heater when the latter has been pretiouslyinstalled.

l/Vhereas I have described my invention by reference to speci'ie formsthereof, it will he 'understood that many changes and ineditieations maybe made without departing from by the I claim:

l. AWater heater comprising a burner. a casing, a vertically extendinghollow coil tor the passage o't the water and disposed above saidburner, a hollow passage member disposed above said burner and Withinsaid coil, anoutflow passage member 'for the outflow of heated waterJfrom said coil and from said hollow passage nienibe and a T-eoxineetioncoininunififatineA with said coil and said hol low passage member andsaid outllow pas sage member.

2. A. water heater comprising a lnnfner` :i casing, a verticallyextending' hollow eoil 'l3nthe passage oit the water and disposal abovesaid burner, a vertically extending passage member disposed above saidburner :ini-l within said coil, an outflow pas. e member and aT-connection connecting: sind efnl and said hollow passage member ineennnon with said outflow passage member.

water heater comprising' a burner. a casing, a vertically extendinghollow eoil 'for the pa ssa gre ol the water and disposed within saidcasina.,- above said burner, a tube elem-ll at its lower end, a secondtube eaienlliznr within said first named tube and coinlnxini eating atone end with the interior oli said irst named tube, an outflow passagemember 'for the outliow oi the heated water and :i T-connection betweensaid eoil` the other end of; said second named tube and said ouille-wpassage member.
